It was a bit on the nose.
An Airbus A330-300 bound for London from Philadelphia was forced to divert to Boston Airport, due to an unbearable smell in the cabin.
According to the airline, the AA728 flight was forced to divert around 90 minutes after taking off on Sunday evening.
The plane had been carrying 154 passengers and 12 crew members, and was due to arrive at Heathrow Airport.
In a statement, American Airlines said ten of the crew members asked to be taken to hospital for a medical assessment after landing.
No passengers reported feeling ill.
While the source of the odour has not yet been established, a maintenance team were put to the case after the plane landed on Sunday night.
